partitioning - Wrong logical/physical sector size can lead to file corruption? - Ask Ubuntu


i'm experiencing continuous file corruption problems have run fsck every time start ubuntu 16.04. :( :( :(

recently, bought second new 1tb hard disk , reinstalled everything. after few days problem again there... system boots not usable (today i've got lot of folders mounted in read-only mode...)

i've made checks trying detect hardware problem (memtest, prime95, gsmartcontrol, bios upgrade, etc) didn't find fault. temperature of teh cpu quite stable.

could adopted partitioning problem?

disk /dev/sda: 931,5 gib, 1000204886016 bytes, 1953525168 sectors units: sectors of 1 * 512 = 512 bytes sector size (logical/physical): 512 bytes / 4096 bytes i/o size (minimum/optimal): 4096 bytes / 4096 bytes disklabel type: dos disk identifier: 0x583cc96a  device     boot    start        end    sectors   size id type /dev/sda1  *        2048    7999487    7997440   3,8g 82 linux swap / solaris /dev/sda2        8001534 1953523711 1945522178 927,7g  5 extended /dev/sda5        8001536   47060991   39059456  18,6g 83 linux /dev/sda6       47063040 1953523711 1906460672 909,1g 83 linux  partition 2 not start on physical sector boundary.

i read misaligned logical/physical sector size can impact on performances. nevertheless read case of pcs not booting @ all. true? should not waste further time , buy new pc? :( :( :(
